Immediate Loading of Implants in the Aesthetic Zone Using Three-dimensionally Printed Provisional Crowns: a 1-year Prospective Case Series Study

Netherlands30 participantsStarted 2026-07-01

Plain-language summary

• Background There is a growing tendency to place a provisional crown immediately following implant placement. Clinical advantages are shortening of treatment duration and soft tissue guiding during healing resulting in better aesthetic outcomes. It was shown that good esthetic results can be achieved on the long term with immediate provisionalization of single-tooth implants placed in either fresh extraction sockets or after alveolar ridge preservation/reconstruction in the maxillary esthetic zone. One recent development in three-dimensional printing is digital press stereolithography (DPS), which overcomes the challenges of printing highly-filled viscous materials. This enables the use of more durable materials than traditional three-dimensionally printed provisional crowns and allows for rapid additive production of prosthetic restorations. Until date, no studies have been described investigating immediate loading of implants in the aesthetic zone using three-dimensional DPS-printers and their impact on patient-satisfaction. * Main research question The purpose of this one-year prospective case series study is to perform an assessment of patient-reported outcomes of single-tooth implants with immediate provisionalization using three-dimensionally printed provisional crowns. * Design (including population, confounders/outcomes) The study design is a prospective, single-arm observational study for evaluation of 30 patients with a failing tooth in the maxillary aesthetic region to be treated with an implant-supported provisional and definitive restoration by means of a provisional and definitive crown. Outcomes: registration of time/complications during the diagnostic/planning/manufacturing process, evaluation of clinical and radiographical performance and aesthetic outcome. * Expected results Satisfying results for patients and professionals (VAS-scores and PES/WES-scores)

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Inclusion Criteria: * The patient is 18 years or older; * The implant region is an incisor (central or lateral), cuspid or first bicuspid in the maxilla; the adjacent teeth are natural teeth; * Sufficient healthy and vital bone after alveolar ridge preservation to insert a dental implant with a minimum length of 10 mm and at least 3.5 mm in diameter with initial stability \> 45 Ncm; * The implant site must be free from infection; * Adequate oral hygiene (modified plaque index and modified sulcus bleeding index ≤ 1); * Sufficient mesio-distal, bucco-lingual, and interocclusal space for placement of an anatomic crown; * The provisional crown can be designed free from occlusal contact; * The patient is capable of understanding and giving informed consent. Exclusion Criteria: * Medical and general contraindications for the surgical procedures; * Presence of an active and uncontrolled periodontal disease; * Bruxism; * Smoking * A history of local radiotherapy to the head and neck region.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
